Separate the areas for digital and analog modules so that addresses do not
overlap. Communications processors (CPs) and intelligent I/O modules
(IPs) count here as analog modules.
Determine the structure of your stations. Additions and changes that you
make later result in address assignments that can be confusing to read or
otherwise unclear.
